摘要
Exclusive production of vector mesons was studied with the HERMES spectrometer at the DESY laboratory by scattering 27.6 GeV longitudinally polarized electrons or positrons off unpolarized hydrogen and deuterium as well as off transversely polarized hydrogen internal targets. Results of the measurements of the Spin Density Matrix Elements ( SDMEs) for rho(0) and phi, the ratios of helicity amplitudes for rho(0) on unpolarized H and D targets as well as of the transverse target spin asymmetry (A(UT)) for omega and phi production on a transversely polarized H target will be reported.
